Suppose the current state of your folder is like this:
project
main.py
numpy.py
When used at the beginning of main.py:
import numpy as np
It will first find and import the numpy files in the current directory.
And if all you really want is to import the standard numpy library, you need to write:
from __future__ import absolute_import
import numpy as np
If you have added absolute_import, but want to import numpy files in the current directory, you need to write:
from __future__ import absolute_import
from project import numpy as np
